How to change units from mm to inches in Automaker?

[robyneil @robyneil My Robox is a Blue Commercial Version]

Hi everyone. Merry Christmas and Happy Holidays!

I’m new here and just got my Robox…9 days running. I’m from California as you can tell from the topic title. So far very happy with it…big fan. I have an AutoMaker question. Does anyone know how to change AutoMaker’s default units of measure from mm to inches?

I’m using SketchUp Make to create models but I notice that if I use “inches” in SketchUp, the model I import in AutoMaker has to be scaled to approximately ~2540% (1in=25.4mm) to get it to the actual size intended. If I use “mm” as the units of measure in SketchUp and export to .stl or .obj, I have no problems importing to AutoMaker and is scaled correctly in the model viewer at 100%. I’ve seen forum members mention inch units in postings so there’s probably a way to do it.

I have either exporting in mm or scaling 2540% as a workaround, but just wanted to test whether changing the units in AutoMaker itself fixes the import of .stl or .obj that has inches as units of measure. I don’t know if this a problem in the file format or in AutoMaker. If AutoMaker, I’ll gladly file a support ticket. Either case, I think AutoMaker should handle units of measure conversions automatically.

I attached the test models (24,5mm x 24.5mm x 6.35mm with a 12.7mm bore) I’m using to test accuracy and calibration.

Other Notes: PLA Draft Print is accurate only on the first few layers of the print with a width of ~25.4mm. Up to ~3% Warping and shrinking on the width on subsequent layers as expected I think. The 12.7mm bore has shrunk by about ~7%. Printing at 107% the bore is a perfect fit for 0.5in or 12.7mm aluminum tubings, but the outer width increased by 4-6% . Hoping to get Cura slicer for Christmas or soon to test how much better slices are with AutoMaker 1.01.

Manifesting ideas is still difficult, but at least we're one step closer...

That is interesting. I have been using SolidWorks on most of my prints and have brought in several other models of both imperial and metric units and have only have one problem that I had to scale around. There is no place to change that I am aware of; to my knowledge it is automatically dealt with in AM.

Thanks for the quick response. I’ll try out SoldWorks since it is compatible with AutoMaker’s import..also to see if scaling is better on it. On Sketchup, I noticed that I have to scale height by 10% as well when using PLA Draft. But knowing now how to adjust for, I get good accurate prints now.
